As the use of teams has increased in organizations, research has begun to focus on the role of leadership in fostering team success. This review sought to summarize this literature and advance research and theory by focusing on leadership processes within a team and describing how team leadership can arise from four distinct sources inside and outside a team. Then, drawing from this inclusive, team-centric view of leadership, the authors describe 15 team leadership functions that help teams satisfy their critical needs and regulate their behavior in the service of goal accomplishment. This integrative view of team leadership enables the summarization of past research and identification of promising areas of future research.
